From State Street in Hurricane take 1760 W south to 400 S. Turn south on 1530 W and travel up the hill to the end.
There is no distinct route around the dome but head towards the east side of the dome and circle the knoll in a clockwise direction returning to the starting point.
In addition to crossing the fence at the start you will need to cross an electric fence and then a wire fence on the west side of the dome.
Here are some pictures along the trek.
